报道了一种采用色散控制腔的被动锁模光纤孤子环形激光器。激光器发射包括变换限制脉冲的强聚束噪声样脉冲。激光发射的光谱具有宽达32.10 nm的带宽。研究发现，仅依靠线性腔相位延迟，激光器就可以在孤子运转和类噪声脉冲发射之间切换。数值模拟结果表明，这种激光辐射是由孤子坍缩和激光器正腔反馈共同作用引起的。
A passively mode-locked soliton fiber ring laser with dispersion managed cavity is reported. The laser emits intense bunched noise-like pulses including the transform limited pulses. The optical spectrum of the laser emission has a bandwidth as broad as 32.10 nm. It was found that purely depending on the linear cavity phase delay the laser could be switched between the soliton operation and the noise-like pulse emission. Numerical simulations showed that the laser emission was caused by the combined effect of soliton collapse and positive cavity feedback in the laser.
